To all whom may concern: 7 I

Be it known that I, CHARLES M. CARLL, a citizen of the United States, residing at Trenton, in the county of Mercer and State of New Jersey, i ve "nvented new and use ful Improvements in Skylight Structures. of. which the following is a specification.

This invention is an improved structure such as e sky-light, glass roof or the one object of the invention being to effect improvements in the construction of the sash, ridge or rafter bars whereby access is afforded to all parts thereof from the inside and said bars are enabled to be painted with out the necessity of removing any of the skylight glasses.

, Another objectoi -the invention is to pro vide a cushion sheet which is arranged between the bars and the sky-light or roof glasses and which serves to form air chamhers that prevent injury to the joints of the structure by condensation of vapors.

Another object of the invention is to efiect improvements in the construction of the bars and in the means for securing them to the supports of thestructure.

nether object-is to effect improvements in the construction of the sheet metal caps which are arranged over the bars and over the contiguous edges of the glass plates.

The invention consists in the construction,

combination and arrangement of devices hereinafter described and claimed.

lln the accompanying drawings: Figural is a vertical sectional viewcf a portion of a shy-light constructed in accordance with my invention. Fig. 2 is a similar View, showing a modification. Fig. 3' is a detail sectional View, showing a construction in which a cross bar and. a gutter are used for more than one glass light. Fig. & is a detail plan of a corner of a sky-light constructed according to my invention.

In the embodiment of my invention I provide channel bars which may be used either rafters of a' struc ture such as a sky-light or a glass roof. Each bar 1 has a longitudinal channel 2 on its under side. Preferably the bars are made of open hearth, ingot, or tungsten steel but may be made of any suitable material. In Fig. 1 I show the invention; as embodied in a sky-light'structure and in hich-the bars are inclined with their inner ends bear ing against" a collar 3 and their outer portions bearing on a curb 4:- To secure the bars-in place I like,

i the bars and 5 arranged on thebars 1 and their tions 12 arranged on opposite sides thereof.

bear on the Webs provide angle brackets 5 which bars, at their inner ends and are secured to the collar by means of bolts 6 and to the upper sides of the bars by means of rivet bolts 7 the heads of which are countersunk in the 7 upper sides of. the bars. These brackets 5 are arranged entirely within the bars and are inconspicuous and may be readily painted together with the inside of all the exposed portions of the bars without the neccssityof removing any of the glass plates.

Where the bars rest on the curb they are secured thereto by brackets 8 which are arranged in the chan are arranged on the inner sides of the Y means of U-shaped nel of said bars and are secured thereto and are also riveted to an lL-bar 9 as shown. These brackets 8 are of less bars so that their upper sides are spaced from the upper sides of the bars tance. The flashing plates on the curb and under the the bars as shown.

side of the cap. The cor v which it is used and. each 1 In Fig. 1 the shy-light braces are shown at 25 with their lower ends securedto the collar 3 by means of the bolts 6.

' In Fig. 2 I show my nvention as applied 5 to a hipped sky-light and in which the ridge bar 1'" has its upper portion bent at an angle as at 2 of the sides of the skylight. The bars 2 which run to the ridge bar are connected thereto by a plate 26 which is bent over the angular upper side ot the ridge baiand has its ends secured on the said bars 9" by bolts 27; said bolts 27 also secure the caps 98 in place. A ridged cap 29 is placed between the ends of the caps 28 and has base flanges 30 which rest on the glass and under the cushionlngsheets 1Q. In Fig. 3 of the (lra wings in which a cross bar and gutter ae uscd'for more than one glass length I show the spaced opflosed ends of glass plates 1 arranged over a gutter 31 g the 'web 32 of which hasa. doubled upstanding strengthening flange Corrugated lead cushioning sheets iii: are arranged be-. tween the said web and the undersldes of the plates, and a flashing plate lies 'on one of the glass plates and has a clownwardly bent portion 36 which extends down to the cushioning sheet and bears between 3 the flange 33 and the end of the other glass sheet.

By means of my improved construction all the exposed portions of the bars and other parts of the structure may be readily painted 35 from the inside without the necessity of removing any of the glass plates.

Having thus described my invention, I claim v 1, In a structure of the class described the combination of a bar, a sheet metal plate to correspond with the pitch,

iomng sheets and ing deflectors at its sides arranged above the condensation gutters, a cushioning sheet on the uppermost sheet metal plate, glass panes bearing on the cushioning sheet, corrugated cushioning sheets on said glass panes, acap plate having depending side walls bearing in the corrugations otthe last named cusha common'securing bolt connecting said bar. metal sheets, the first named cushioning sheets and cap plate together and also clamping the cap plate firmly on the last named cushioning sheets.

in a structure of the class described the ('oi'nbination ot' a bar, a sheet metal plate thereon having condensation gutters arranged on opposite sides of the bar, a second sheet metal plate on the first named sheet metal. plate and having downwardly extending deflectors at its sides arranged above the condensation gutters, a cushioning sheet on.

the uppermost sheet metal plate, glass panes bearing on the cushioning sheet, corrugated cushioning sheets on said glass panes, a cap plate having depending side wallsbearing in the corrugations of the last named cushioning sheets and a common securing bolt connecting said bar, metal sheets, the first named cushioning sheets and cap plate together and also clamping the cap plate firmly on the last named cushioning sheets, a nut bearing on the cap plate and also having a nut bearing on the first named cushioning sheet and henceenabling the cap plate, last named cushioning plates and glassplates to be loosened or'removed independently of the first named cushioning sheets and sheet metal plates.-

In testimony whereof I, afiix my signature in presence of two Witnesses. 7
